U-SHAPED METAL PLATE FOR METAL STRUCTURES.

SPECIFICATION forming part of Letters Patent No. 376,979, dated January24, 1888.

Application tiled ()rtober H, 1987. Serial No. 352,397.

(No model.) Patented in France January 12, 1887, No. 180,850.

To all whom it may concern:

Be it known that I, ERNST DE LA SAUCE, a subject of the King of Prussia,residing at Berlin, in the Kingdom of Prussia, German Empire, haveinvented cert ain new and useful Improvements in U-Shaped Metal Plates,(for which I havcobtaincd Letters Patcntin France, No. 180,850, datedJanuary 12, 1887,) ot'whieh the following is a specification.

Myinvention relates to an improved system of U-shaped metal plates,particularly of sheet iron or steel bent into the form of a U withparallel sides, into which, at or near the bottom, or the bottom andtop, of each side a recess or boss is formed extending through the wholelength of the plate and projecting either outside or inside.

Referring to the accompanying drawings, Figures 1, 2, 3, 4, 5, and 6represent several profiles of such U-shaped metal plates, the height ofthe sides a of which is always larger than the breadth of the bottom I).Suehprofiles are bent from a lint sheet-metal plate of any suitablelength by a special bending-mar chine, which, however, forms no part ofthis invention. At the bottom and top of each of the sides a of aU-shaped bent plate a recess or boss, 0, is formed or pressed into themetal. In Fig. 1 the semicircular recesses c are projecting outside ofthe sides a, and a rounded corner from the plane of the side to theplane of the bottom is thus formed. ,In Fig. 2 they are projectinginside. in Figs. 5 and 6 the corresponding recesses e are angular. InFig. 3 the recesses care formed into the upper and lower edges 01' thesides u 0! the plate, and in Fig. 4 the said recesses c are only formedinto the bottom edges of the plate-sides a.

This improved system of U shaped bent metal plates as an article ofmanufacture is particularly destined for constructing buildings ofvarious kindsuch as sheds, huts, cabins, watchmens houses, and thelike--but also for constructing warehouses, barracks, and buildings of alarger size, tanks, reservoirs, cisterns, and other compartments.

In constructing a buildingor reservoir or the like of such U-shaped bentplates the bottom I) of one bent plate is fitted into the open end ofanother bent plate in such a manner that the bottom recesses c of oneplate enter into the top recesses of another plate, or vice versa, asclearlyshown in Fig. 7. Bythis means the several U shaped bent platesclasp each other, and a series ofsuch bent plates may be united withoutriveting or the like, having a sufficiently strong hold one upon anotherby the recesses fitting into each other; but to give a wall orcombination of such U-shaped bent plates an additional strength rivetsmay be used to unite every two of the bent plates, as shown in Fig. 7.The riveting is done by a special machine. The jointing between everytwo of the bent plates may further be tightened by the application of asuitable packing orjointing or cementing material between the surfacesof the two recesses clasping each other.

For strong metal plates I prefer the profile shown in Fig. 4, in whichthe recesses c are formed only at the lower edges of the sides a of thebent plate. The upperstraight ends of the sides a of the bent plate fitinto the recess 0 of the next plate, as shown in Fig. 8. By

this means I obtain perfectly flush and even 7 surfaces of the wallcomposed of such U shaped bent plates, while with the other profilesribs or webs will project outside or inside, formed by the recesses c.The U shaped bent plates,

thus united with or without the aid of rivets,

form double or hollow walls, the sides of which are kept apart andstiffened by the bottoms I) of the several bent plates, as shown inFigs. 7 and 8. By this means the hollow walls oifcr aconsiderableresistance to any pressure act.- ing against their sides, and are noteasily dcflcctcd and brought out of shape save by great violence. Thehollow space between the two sides a of each bent plate, being filledwith air, which is a non-conductor of heat, offers any required safetyagainst fire, which, attacking the wall on one side, will not be able todestroy the opposite side, owing to the intermediate hollow 'orair-filled space. If convenient, this space between the two sides may befilled up with sand or ashes or any other convenient material,preferably a non-conductor of heat.

In constructing a wall or other part of a building, a tank, reservoir,or the like, the U- shaped bent plates may be arranged headwise,

with their length vertically and one beside another, as shown in Fig. 9;or the bent plates may be horizontally arranged and fitted one into andover another.

In Fig. fl I have shown a door constructed of such Ushaped bent-metalplates. Fig. 10 is a horizontal section of said door along the line at xof Fig. 9. Such doors are fireproof, verylight, and, accordingly,theyturn easily on to their hooks in the frame. The front edge of the door,with the lock, is formed by the bottom 1) of the foremost bent plate.The open back edge is closed by a channel-iron or fiat rail or bar, (I,as also the open top and bottom :5 ends of the door.

In constructing buildings of any kind, or parts of same, or tanks,reservoirs, and the like, the different walls, floors, ceilings, roofs,&c., consisting of the U-shaped bent plates, as

described, may be fitted closely together and united at any desiredangle by the aid of iron beams, girders, rails, angle-irons, or timber,and the like, to which the U-shaped bent plates are riveted, screwed, orfastened by hooks or other convenient means. In a building constructedin this manner of U-shaped bent plates the adjoining walls may easily beso arranged that their hollow insides communicate with each other toform fines or channels which may be utilized as air-conduits or forheating purposes. By this means a thorough ventilating or heating systemmay be established throughout the building without any particular finesand chimneys constructed 3 5 for the purpose.

The bent plates may be galvanized, tinned, or varnished to protect themfrom rust. The inside walls and floors of a building may be lined withwood, if convenient.

In bending the plates into the U-shaped form, as described, and shown inFigs. 1 to 6, additional webs or recesses may be pressed into the metalof the sides a for the purpose of giving them superior strength. Suchadditional webs or recesses, however, are not essential for the purposein view; also, the sides a of the bent plates may be easily provided,while being bent, with haut-relief or has-relief ornaments pressed intothem by the same operation which forms the recesses c.

I claim as my invention 1. As an article of manufacture, metal platesbentinto a U shaped form,with recesses formed into the metal at or nearthe upper and lower end of the sides a, substantially as and for thepurpose set forth.

2. As an article of manufacture, metal plates bent into a U-shaped form,with a recess, 0, formed into the metal at the lower edge of the sidesa, substantially as described, and shown in Fig. 4.

3. The combination of two or more metal plates bent into a U-shapedform, having recesses 0 formed into the metal, such recesses serving togive a hold of one bent plate upon another, substantially as and for thepurpose described.

4. The combination of a series of U section plates, a, havingbottoms Bat right angles to the sides, and recesses or projections C, with aterminal coverplate, (1, whereby a stout noncouducting cellularstructure is obtained,with strengthening-plates b b b w .r d atintervals and at each end.

5. The combination of a series of narrow U- plates, A, with roundedcorners, curved bulges c, and terminal plate d, forming a door, wherebyastrong fire-proofdoor is obtained, having rounded end to allow forradial action, and a series of strong vertical ribs and hollow frame,with a rounded universal joint between each panel capable of allowing ofgreater expansion on one side than the other through unequal heating incase of a fire.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

ERNST DE LA SAUCE.
